On New Year’s Day one of our girl crushes from way back, Lauren Conrad, announced that she is pregnant and we couldn’t be happier for Conrad and husband William Tell, who are excited to welcome their first child.

While Conrad is only in her second trimester, the star is already making a stand for pregnant woman everywhere and in a recent blog post on her website, Conrad got refreshingly real about how to speak to pregnant women. “Most people only mean well when they are commenting on a pregnancy, but it’s one of those situations where it’s hard to know what to do or say,” she wrote. “I may only be in my second trimester, but I’ve already noticed quite a few etiquette missteps when it comes to how people behave around someone who is expecting.”

The number one faux pas? Conrad warns against commenting on the size on a woman’s bump. “Women carry their pregnancy in all different ways, and can be self-conscious about it,” the former The Hills star wrote. “Whether a woman is bigger than average or she’s not showing as much as she thought she would be, keep in mind that it can be a very sensitive subject.”

Just as it would be offensive for a person to comment on the size or body shape of a non-pregnant woman, making comments about a woman’s baby bump is often unwelcome and upsetting. Pregnant athletes like Chontel Duncan have backed this up, highlighting how insecure they felt after being told that their bump was ‘too small’.

In the blog post Conrad also warns against touching a pregnant woman’s bump without permission. “This one might seem like a no-brainer, but every mama I know has some story about a stranger touching her pregnant belly,” she wrote. “Even if you are a close friend or family member, it doesn’t hurt to ask first before making a grab for the belly. No matter what your relationship to the mama-to-be is, keep in mind that it’s much more pleasant to have someone politely ask if it is OK before groping your midsection.”

It seems that when it comes to pregnant women, people tend to forget the simple rules of etiquette and Conrad hopes to remind people that just because a woman is pregnant, it does not mean that it is okay to throw the rules out of the window. “A lot of people may think that the idea of etiquette is an old-fashioned concept, but even in modern times a little politeness still goes a long way,” Conrad concluded.
